[N6426K]
Southwick, Maine. During flight, the engine begun to run
rough. The pilot attempted to correct the situation but the engine
continued to operate at reduced power. He elected to land the
amphibious plane in a field and extended the gear. However, the
pilot saw that the aircraft would not clear trees, so he decided to land
on a nearby lake. There was not enough time to retract the gear;
therefore, during the landing, the plane flipped over. It
continued to float, and later, it was turned to an upright position and
towed out of the lake on its gear. The pilot stated that he had
drained the sumps before the flight. After the accident, he
drained about 5 ounces of fluid from the upper drain and about half of
it was water. However, the water was found after the aircraft had
floated upside down in the lake over night. Injuries: 1 Minor, 1
Uninjured. [NTSB Identification: NYC82DA156].
